SPECIFICATION forming part of Letters Patent No. 491,586, dated February 14, 1893.

Application filed May 18, 1892.

To all whom, it 11mg concern.-

Be it known that I, OLE PETERSON, a citizen of the United States of America, residing at Hinsdale, in the county of Du Page and State of Illinois, have invented certain new and useful Improvements in Paper Trimming and Pasting Machines, of which the following is a specification.

My invention relates to improvements in paper trimming and pasting machines, its object being to provide a simple and practical machine adapted to trim the edges of wall paper and at the same time to apply a suitable coat of paste to the blank face thereof.

The invention is fully described and explained in this specification and shown in the accompanying drawings, in which- Figure 1 is a top plan of a machine embodying my invention, parts of the machine being broken away to show construction; Fig. 2 is an end elevation of the machine, the viewbeing in the direction indicated by the arrow y, Fig. 1; Fig. 3 is a front elevation of the machine, the view being in the direction indicated by the arrow y, Figs. 1, 2; Fig. 4 is a vertical section of the machine, the plane of section being through the line 0c0c, Figs. 1, 3; Fig.5 is avertical section through the line 0c-a', Figs. 1 and 3, the supplemental table A being folded up over the top A, of the main table; Fig. 6 is an enlarged elevation of one of the clasps H, with its finger h, the

View being in the direction indicated by the arrow y, Fig. 1.

In these views, A, A are the ends, A is the top and A is the bottom of a box containing or supporting all the working parts of my machine, and A A are folding side pieces hinged to the bottom A and adapted to form sides for the box, or to be dropped down to the position shown in Figs. 2, 3, A, and form the supports thereof, thus bringing the top A',of the box to a suitable working height. The two pieces A are provided with eyes fastened to their ends and when they are dropped down, these eyes receive hooks at the ends of a rod a, and are thereby suitably connected. When the side pieces are raised to form part of the box, they receive hooks a, Fig.2, fastened to the end pieces A, and are thus held in their raised position. A supplemental top A is hinged to the edge of the top A, and maybe Serial No. 433,487- (No model.)

raised to the position shown in Fig. 5, or dropped to the position shown in Figs. 1, 2, 3, 4, to increase the top surface of the table. When thus dropped down it is supported by a sliding bracket a moving in guides a Fig. A, and adapted when not in use to lie wholly beneath the top A, of the box.

To the end pieces A, A, and near their rear edges are pivoted two brackets 12, 1), adapted to receive and supporta horizontal rod 13, and this rod is provided with cutters in the form of disks Z2, so constructed as to bereadilydetachable from the rod or adjustable upon it. The rod is adapted and intended to receive a roll of wall-paper P, and the disks serve to hold the roll in place and to fix its longitudinal position upon the rod. The brackets 19, b, are adapted tolie in the position illustrated in Figs. 2 and 4, or to be swung upward, thereby bringing the shaft, B, wholly within the box. Spring levers L, L, are pivoted to the top A, of the box and provided with friction plates, Z, Z, Fig. 8, adapted to press upon the roll P, and prevent accidental unrolling of the paper. lVhen-in use, the levers project beyond the edges of the box, but when the machine is not in use they may be swung about their pivots until they lie wholly in the box, so that the side pieces may be swung upward and secured in place in the manner hereinbefore described.

To the inner faces of the end pieces A, A, are rigidly fastened two cast frames, M, M,

front of the rod B, are journaled two shafts B, 13 connected by gear-wheels G, G, the shaft B being provided with a crank 19 by which it may be turned, and the gear-wheels being intended to insure equal and reverse rotation of the two shafts. On the shafts B, B are adj ustably mounted three sets of coacting cutting disks, D, D, D, D, 0 D intended to be used two sets at a time for trimming the edges of a roll of paper, or three sets at a time for trimming the edges of the roll and slitting it longitudinally on any desired line at the same time. In front of the shafts B, B, are two other shafts B B supporting feed-rolls R, R, the shaft B being mounted in stationary hearings in the frames M, M, and the shaft 8, being mounted in sliding bearings in the frames as shown in Fig. 4. The

and in these frames at a suitable distance in.

shaft 13 is provided with a gear-wheel engaging the gear-wheel C, so that the rotation of the crank b rotates the feed-rolls which are intended to draw the paper forward from the roll P, the paper being carried from the roll P, between the cutting disks D, D then over the roll R, then between the rolls R, R,

and then about the rear face of the roll R, and toward the front of the machine.

Below the roll R, and slightly in front ofit is a pasting roll R mounted on a shaft B which is journaled in the frames M, M, the pasting roll being within a suitably supported paste-box E, intended to be filled with paste to a level above the lower margin of the roll. The shaft B of the paste roll is provided with a gear-wheel O engaging the gear-wheel C of the feedroll and thus imparting rotation'to the paste roll, and the paper being carried forward from the feed-roll R, over the paste roll R receives on its lower face the paste brought up by the paste roll in its rotation. In front of'the paste roll and near the front edge of the box lie a scraper F, and a small guide roll R supported by brackets f, f, pivoted to the end pieces of the box by means of thumb screws, f, Figs. 1, 2, and

adapted to be adjustable by rocking them of the end pieces A, A.

upon their pivots. The'paper is carried forward from the paste roll over the scraper F, and under the guide roll R and thence upward to another guide roll R mounted in brackets b b nearthe upper front corners The adjustment of the bracketsfif, raises or lowers the scraper F, with reference to the guide roll R the effect of the raising of the scraper being to press it more closely against the surface of the paper and thus to remove the paste more thoroughly and leavea thinner coat upon the paper, and, on the other hand, if the scraper be dropped down the thicker coat of paste adheres to the paper. The brackets 19 which support the guide roll R are pivoted to the end pieces of the box and may be raised to the position shown in Fig. 47, or swung downward to bring the roll wholly within the box/ When raised they are held in place by means of springs S, S, fastened to the end pieces of the box and engaging notchesin the edges of the brackets as shown in Figs. 4 and 5. The paper carried from the guide roll R to .the guide roll R passes in front of the latter and then over it and is carried thence back over the top A, of the machine and the supplemental top A the pasted side of the paper being upward. A knife K, is pivoted to the top A, atone side of the path of the paper and is held normally in a vertical position by means of a spring S, but may be pressed down across the paper in the manner illustrated in Figs. 1 and 3 when it serves as means for tearing the paper at right angles, to its length.

The machine as thus far described is adapted to trim the paper, paste its blank sideand cut it into suitable lengths, and for these purposes is practically operated and very convenient and useful. I have found it very advantageous, however, to provide the machine with means for folding the paper upon itself in order that it may be more conveniently handled and carried from the machine to the wall upon which it is to be spread. For this purpose I have attached to the machine two sets of gripping devices, one set being placed at the rear edge of the supplemental table A, and the other at the rear edge of the top A. The set atthe rear edge of the supplemental table comprises two plates H, H, swinging on pivots parallel to the edges of the paper, each of the platesbeing provided at its upper end with a finger h, adapted to drop down over. theside edges of the supplemental table A and over the edges of the trimmed and pasted paper, as shown in Figs. 1, 2, 3, 4. The lower ends of the plates H, H, are connected by rods g, g, with a horizontally oscillating plate G, pivoted to the lower surface of the top A and provided with a handle G, by means of which it may be turned. The partial rotation of the handle G, and plate G swings the plates H, II, upon their pivots and raises and. lowers the fingers h, h. The set of gripping devices at the edge of the top A, is made up of two plates H, swinging on pivots parallel to the edges of the paper, each of the plates being provided at its upper end with a finger h", adapted to swing down over the edge of the paper. The lower ends of the plates H, are pivoted upon rods 71. Fig. 5,. parallel to. the edges of the paper, these rods being beneath the top A, and their front ends being fastened thereto, while their rear ends engage the plates HQH, and are provided with upturned ends 7L3, Figs. 3, 5, 6, lying beneath the supplemental top A WVhen the supplemental top A is down as shown in Figs. 3, 0, it depresses the ends h of the rods 72?, thereby depressing the lower ends of the plates H, H, and raising the fingers h, h. As the top A is raised, however, its pressure is removed from the ends lbs, of the rods 72?, and springs S ,IFig. 6,.press the lower ends of plates H, upward and bring the fingers h, down across the edges of the paperas shown in Fig. 5.

Then it is desired to fold the paper-the fingers h, 71, at the rear edge of the table A are pressed down upon the paperin the mannershown in Figs. 1, 2, 3, thereby holding the end of the strip of paper firmly in position. The'table A is then raised and permits, the fingers h, h, to drop down over the edges of the paper at points on the lineof the rear edge of the top A. The top A, is then thrown to the position shown in Fig. 5, doubling the paper over the two fingers h, h, and bringing the fingers h, h, between the two folds of the paper. These fingers are then withdrawn from the paper by turning the handle G, and are then thrown under the lower fold of the paper by reverse rotation of thehandle. The

supplemental table is then swung back to the position shown in Fig. 4, drawing a new layer of paper the entire length of the table, and the operation of folding is repeated again and again until a strip of sufficient length has been drawn through the machine and folded upon itself. The strip may then be severed by means of a knife K, and taken from the machine.

I am aware that various details of construction of this machine may be varied without departing from its principle of construction and operation, and I desire therefore not. to limit my invention to the exact forms shown and described herein, or in any way, except as the invention is defined in the following claims.
